STAR alignment with multiple fq files
 

I am trying to do RNAseq PE alignment using STAR. It works for one pair of fq files:

$ STAR --runThreadN 30 --genomeDir /srv/STAR_genome/human/ --readFilesIn /../RNA4_1_R1.fastq.gz /../RNA4_1_R2.fastq.gz --readFilesCommand zcat

However, I have multiple fq files for one sample and I need to align them into one sam file. When I tried to align all together, it returns 'Segmentation fault (core dumped)':

$ STAR --runThreadN 30 --genomeDir /../STAR_genome/human/ --readFilesIn /../RNA4_1_R1.fastq.gz /../RNA4_1_R2.fastq.gz /srv/RNA4_2_R1.fastq.gz /../RNA4_2_R2.fastq.gz --readFilesCommand zcat
Segmentation fault (core dumped)

Could STAR deal with multiple pairs? What am I missing, pls?

Sorry I figured it out. But I don't know how to delete the post.

Could you please share? Thank you
